SECTIONAL-RING FRlCTlONAL ROLLER FOR LEATHER-SPLITTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 777,248, dated December13, 1904:.

Application filed May 23, 1904. Serial No. 209,306. (No model.)

To all whom it may concern:

Be it known that '1, JAMEs WILLIAM DECK- ER'I, a citizen of the UnitedStates, residing at Morristown, in the county of Hamblen and State ofTennessee, have invented certain new and useful Improvements inSectional-Ring Frictional Rollers for Leather-Splitting Machines; and Ido declare the following to bea full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to new and useful improvements in sectional-ringfriction-rolls for use on band or belt knife leather-splitting machines;and the object of the invention is to produce an apparatus whereby moreperfect and finished split leather may be produced than by the machinescommonly employed.

More specifically, the invention comprises a friction-roll made up ofsections mounted upon a flexible cable having ball-and-socketconnections with suitable anchorage members and so arranged that as thehide passes be tween the gage-roll and the sectional roller and againstthe splitting-knife the sections of the friction-roller will be adaptedto bear against a rubber cylinder and by two or more of the sectionsyielding together to produce an undulating surface to the leather whenuneven portions thereof come in contact with the sections of the rollerwithout presenting sharp corners to the leather, as is commonly a faultwith sectional friction-rollers now in use upon machines of thischaracter.

My invention consistsfurthelgin various de tails of construction and incombinations and arrangements of parts, which will be hereinafter fullydescribed and then specifically defined in the appended clail'ns.

My invention is illustrated in the accompanying drawings, in which--Figure 1 is a front elevation of a portion of a leather-splittingmachine, showing the relative positions of the sectional roller, thegage, and rubber roller. Fig. 2 is an enlarged longitudinal centralsectional view through the drawings by letter, A indicates the frame ofan endless-belt leather-splitting machine having the general features ofthe usual machines of this character, provided with a sup iporting-roller B, suitably journaled in the frame and upon which thecushion-roller (l rests.

I) designates a gage-roller, and E designates a block having a socket Ein one face thereof, and said block is fastened to the frame'by means ofbolts F. Each of said blocks E, there being one upon each opposite sideof the frame and of similar construction. has an aperture 6 leadingthrough the same, the walls of said apertures being tapered, as shown inthe detail sectional view of the drawings, and each socket member E isadapted to receive an end of a flexible wire cable H, each end of saidcable having a ball K either integral therewith or secured to the endsof said cable, and said balls are adapted to have bearing in therecessed socket portions of said plates, as shown in the detail view ofthe drawings, and the tapering walls of the apertures c are for thepurpose of allowing the cable to yield in different directions, as willbe understood. Mounted upon said cable is a series of sectional rings N,which to all outside appearance are similar to the usual sectional ringsemployed upon rigid rods 01' shafts; but each of said sections N uponreference to the sectional view of the drawings will be seen is providedwith a concaved recess N in one end, while the opposite end convexed, asat 0, adapted to conform to the concaved recess of the adjacent end of asection in which it is adapted to nest, as shown in the sectional viewof the drawings. Each of said sections is apertured, the walls of whichare provided with threads Q for the purpose of fitting upon the spindlewhen it is desired to true the same when the various sections becomeirregular from wear. After the sections are placed upon the cable in themanner shown and described they are held interlocked by means of thecollars R, one being held in contact with each end of the series ofsections and fastened to the cable by means of a set-screw R.

By the provision of a roller embodying the features of my invention itwill be observed that when hides are passed between the sectional andgage rollers and when uneven portions of the hide contact with one oranother of the sections of the roller one or more of said sections willyield slightly, forming an undulating surface which will not leave marksupon the hide, as is commonly the case where but one of the sectionsyields independent of the others, thus leaving a sharp corner orshoulder which has a tendency to leave an impression upon the hide. Inthe drawings I have shown a diagrammatic view illustrating theundulating surface side by side with the surface that is afforded byoffsets or shoulders in the machines commonly in use. As .the pressureis removed from the undulating surface caused by uneven surfaces ofhides passing between the sectional frictional roller and the gage theelasticity of the cable will serve to return the sections to theirnormal positions.

While I have shown a particular detailed construction of apparatusillustrating the features of my invention, it will be understood that Imay vary the same, if desired, as to certain differentiations without inany way departing from the spirit of the invention.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is

1. In combination with a leather-splitting machine having the usualgage-rollers, cuttin g-knife and yielding cylinder, a flexible cablehaving ball-and-socket joints at its ends and positioned intermediatesaid cylinder and knife, a series of interlocking cylindrical sectionsmounted upon said cable and adapted to present an unbroken undulatingsurface to a hide passing between said sections and gageroller, as setforth.

2. In combination with a leather-splitting machine having the usualgage-roller, cuttingknife and yielding cylinder, a flexible cablepositioned intermediate said cylinder and knife, the ends of which cableare formed with balls, apertured socket members through which said cablepasses and in which said balls have bearings, the apertures in saidsocket members being tapered, a friction-roll made up of a series ofsections interlocking with one another, and means for holding saidsections interlocked, whereby as uneven portions of hides are passedbetween the friction and gage rollers, an unbroken, und ulating surfaceis presented upon the friction-roller, as set forth.

3. In combination inaleather-splitting machine, the gage-roller,yielding cylinder and cutting-knife, socket members secured to the frameof the machine, a flexible cable intermediate said cylinder and knifeand having sockets in which the balls at the ends of said cable havebearings, a friction-roller made up of apertured sections strung uponsaid cable, one end of each section being concaved and the opposite endconvexed, collars adapted to hold said sections interlocked, andset-screws carried by said collars and adapted to hold the latteragainst said cable, as set forth.

In testimony whereof I hereunto afiix my signature in presence of twowitnesses.

JAMES WILLIAM DECKERT.
